First report of chocolate spot disease on broad bean (Vicia faba) caused by Botrytis fabiopsis in Japan, and the draft genome sequence of the pathogen.

Broad bean chocolate spot (BCS) is an economically important disease of broad bean ( Vicia faba ). In 2022, we collected broad bean leaves showing disease symptoms from a field where the typical BCS observed. Isolated fungus exhibited pathogenicity on broad bean leaves, producing with typical BCS symptoms. Whole genome sequencing and phylogenetic analysis using G3PDH , HSP60 and RPB2 gene sequences identified the isolated pathogen as Botrytis fabiopsis . This is the first report of B. fabiopsis causing BCS on broad bean in Japan, and also the first report of its draft genome sequence.
